DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

The present invention provides a carbonated beverage apparatus, as shown in FIG. 1A to FIG. 7, which is controlled by a chilling system to make frozen beverage. As shown in FIGS. 1A and 1B, the frozen beverage mixing arrangement comprises a freezing cylinder 10 and a stirring pusher 20 disposed inside the freezing cylinder 10 to push and mix a mixture 30 from an inlet 11 to an outlet 12 in an inner spiral manner. Furthermore, the stirring pusher 20 is driven by a motor 200 to be rotated in the freezing cylinder 10 along a driving axis 201 of the stirring pusher 20 which is the same as the centerline axis of the freezing cylinder 10. When the stirring pusher 20 is rotating, the mixture 30 is being pushed to move from the inlet 11 to the outlet 12. And as the outlet 12 is opened, the mixture 30 is served as frozen beverage flowing out of the mixing arrangement.

Furthermore, the freezing cylinder 10 is firstly fed with ingredients of the mixture 30 which is flowed inside the freezing cylinder 10 with being mixed into the mixture 30. The freezing cylinder 10 has an inner wall 110 contacted or touched by the stirring pusher 20. As the mixture 30 is chilled and tends to attach on the inner wall 110, which is willing to get frost on the inner wall 110, the mixture 30 is capable of being moved from the inner wall 110 back into the freezing cylinder 10. So the stirring pusher 20 pushes the mixture 30 to move forwards and inwards in the freezing cylinder 10.

As shown in FIGS. 1A and 1B, the stirring pusher 20 further comprises a beater device 21 and a baffle 22 positioned surrounded by the beater device 21. The mixture 30 injected from the inlet 11 is pushed to move in the inner spiral manner by beater device 21. The mixture 30 moves along the freezing cylinder 10 while being chilled from the inlet 11 to the outlet 12 and along the direction of from the inner wall 110 to the baffle 22 inside the beater device 21. So the mixture 30 is moving along an inner spiral line pushed by the beater device 21, and the baffle 22 is blocked the flowing path of the mixture 30 to evenly mix and smash to make the frozen beverage. Accordingly, the beater device 21 is arranged to radially stir and move the mixture 30 from a peripheral portion of the freezing cylinder 10 to a center portion thereof, while the baffle 22 is arranged to stir the mixture 30 within the center portion of the freezing cylinder 10.

What is more, the beater device 21 further comprises a supporting frame 211, a helical paddle 212 and a scraper blade 213, wherein the helical paddle 212 is fixed on the supporting frame 211 in order to be rotated to push the mixture 30 moving, wherein the scraper blade 213 is detachable mounted on the supporting frame 211. The helical paddle 212 is rotated with the supporting frame 211 to generate a pushing force to the mixture 30 inside the freezing cylinder 10. It is worth to mention that the helical paddle 212 of the beater device 21 is not contact or touch the inner wall 110 of the freezing cylinder 10. The scraper blade 213 contacts or touches the inner wall 110 so that the helical paddle 212 hardly wear out against the freezing cylinder 10. And the mixture 30 is flowing between the helical paddle 212 and the inner wall 110 and into the inside helical paddle 212 to the baffle 22.

As shown in FIG. 2, the scraper blade 213 is supported to touch the inner wall 110 of the freezing cylinder 10. When the supporting frame 211 is rotated, the scraper blade 213 is moved to press against the inner wall 110 so that the mixture 30 attached on the inner wall 110 is capable of being removed. Not only the mixture 30 attached on the inner wall 110, the mixture 30 around the inner wall 110 is capable of being radially moved to inside of the freezing cylinder 10 and to the baffle 22 inside the beater device 21, as shown in FIGS. 4A to 4C.

Furthermore, the supporting frame 211 further comprises at least two elongated rods or members 2112 extended parallely in the freezing cylinder 10, at least one arched connector 2113 fixed between the elongated rods 2112, and a driven end 2111 formed on one of the end of the elongated rod 2112. The driven end 2111 is connected to the motor 200 to drive the elongated rods 2112. The arched connector 2113 is connected one of the elongated rod 2112 to another elongated rod 2112 so that the elongated rods 2112 is secured with each other while rotating. And the arched connector 2113 is adapted to enhance the position between the elongated rods 2112 and decrease retention of the mixture 30. Since the arched connector 2113 and elongated rods 2112 have continuous surfaces, the mixture 30 is hardly to be stocked inside the supporting frame 211.

As shown in FIG. 3, the supporting frame 211 further comprises a scraper gripper 2115 formed on the arched connector 2113 to hold the scraper blade 213 to be rotated with the supporting frame 211. The scraper gripper 2115 is preferably integrally formed on the arched connector 2113. The scraper gripper 2115 further comprises a gripping slot 21151 and a projection 21152 protruded from the gripping slot 21151. The gripping slot 21151 is adapted to receive the scraper blade 213 inside and hold the scraper blade 213 securely. The scraper blade 213 has a mounting hole 2130 through the scraper blade 213 and is respective to the projection 21152 of the scrapper gripper 2115 so that the scraper blade 213 is positioned by the projection 21152. The scraper blade 213 is mounted on the scraper gripper 2115 with the projection 21152 inserted in the mounting hole 2130 so that the scraper blade 213 is securely supported in the gripping slot 21151. It is easy to mount or detach the scraper gripper 2115 with inserting the projection 21152 or pulling out the projection 21152 off the mounting hole 2130.

It is worth mentioning that the gripping slot 21151 is adapted to hold one of ends of the scraper blade 213 when rotating with the supporting frame 211. And the other end of the scraper blade 213 is pressed against the inner wall 110 to remove the mixture 30 back to the center of the freezing cylinder 10, as shown in FIG. 4A to FIG. 4C. As the supporting frame 211 is driven by the motor 200 from the driven end 2111, the scraper blade 213 is moved along and pressed against the inner wall 110. The mixture 30 attached on the inner wall 30 is likely to be frosted with ice on the inner wall 110. The scraper blade 213 is rotated to press on the whole inner wall 110 in a circle. The scraper blade 213 may not remove the mixture 30 once a time, and may slightly adjust the angle between the scraper blade 213 and the gripping slot 21151. When the scraper blade 213 is rotated to shave a little of the frost mixture 30 in a rotating circle, the scraper blade 213 is continued to be rotated. When the scraper blade 213 is rotated to push the mixture 30 around and around, the mixture 30 will be removed from the inner wall 110. So if the mixture 30 attached on the inner wall 110 is a large one, the scraper blade 213 is capable of gradually removing the mixture 30 with the scraper blade 213 hold in the gripping slot 21151. The frosted mixture 30 may be shaved little by little or be shaken around by around. It is worth to mention that the scraper blade 213 is retained in the gripping slot 21151 with the mounting hole 2130 inserted with the projection 21152. The gripping slot 21151 provides adjustable movement for the scraper blade 213 with the projection 21152 positioning the scraper blade 213. The scraper blade 213 is adjustably pivoted around the projection 21152 in the embodiment to have different angles in the gripping slot 21151. It is also easy to mount the scraper blade 213 into the gripping slot 21151 by looping in the projection 21152. The radius of scraping circle of the scraper blade 213 is fine-tuning while rotating against the inner wall 110 to scrap the frosted mixture 30.

The beater device 21 is moving the mixture 30 from the inlet 11 to the outlet 12 by the helical paddle 212 and from the inner wall 110 to the center of the freezing cylinder 10 by the scraper blade 213. Especially, the beater device 21 is forced on mixing and pushing the mixture 30 in the freezing cylinder 10. The baffle 22 inside the beater device 21 is blocked the flowing path of the mixture 30 so as to smash the ingredients of mixture 30 into pieces and stir the ingredients of mixture 30 back again to evenly mix the mixture 30. Thus, the mixture 30 is moving along the inner spiral line pushed by the beater device 21 and bumped into the baffle 22.

The baffle 22 has a first end 221 and a second end 222, as shown in FIG. 5, wherein the first end 221 is received in one end of the freezing cylinder 10, wherein the second end 222 is statically disposed on the supporting frame 211 respectively. In other words, the baffle 22 is stationary while the beater device 21 is rotated. When the supporting frame 211 is rotated driven by the motor 200, the baffle 22 is static respective to the supporting frame 211. In order words, the supporting frame 211 is rotated around the baffle 22, and the first end 221 and the second end 222 of the baffle 222 is retained static against the freezing cylinder 10. The beater device 21 is connected to the driving axis 201 rotatably powered by the motor 200 while the baffle 22 is independent from the driving axis 201 that the baffle 22 is not connected to the driving axis 201. The supporting frame 211 further comprises a holder 2114 connected between the elongated rods 2112. The second end 222 of the baffle is disposed in the holder 2114, which is indirectly connected to the motor 200. Thus the baffle 22 is less suffered friction with the motor 200 to sustain long life-time. The holder 2114 provides relatively static with the supporting frame 211 when rotating.

Furthermore, the holder 2114 comprises a holding frame 21141 and a bearing 21142, wherein the holding frame 21141 is connected the bearing 21142 with the elongated rods 2112 so as to support the bearing 21142 and the second end 222 near the driven end 2111 of the supporting frame 211. The second end 222 of the baffle 22 is holding in the center of the bearing 21142, and the whole bearing 21142 is supported by the holding frame 21141. As the supporting frame 211 is rotating along the driving axis 201, the second end 222 of the baffle 22 is kept static in the bearing 21142 of the holder 2114. In order words, the bearing 21142 transforms rotation from the holding frame 21141, the supporting frame 211 or the motor 200 into satiation of the second end 222 of the baffle 22. Therefore, the mixture 30 is moved in the inner spiral manner to be crashed on the baffle 22 for evenly mixing. The mixture 30 is pushed inside to bumped into the baffle 22 to be smaller pieces, and be flushed out of the baffle 22, and be pushed by the beater device 21 back to the baffle 22, which is a flowing cycle of the mixture 30. After several flowing cycles around the baffle 22, the mixture 30 is pushed from the inlet 11 to the outlet 12 to be prepared as frozen beverage.

An alternative mode of the stirring pusher 20′ of frozen beverage mixing arrangement according to the above preferred embodiment of the present invention is illustrated as in FIG. 6. The stirring pusher 20′ comprises a beater device 21′ which is similar with the beater device 21 according to above embodiment, and a baffle 22′ arranged inside the beater device 21′.

The baffle 21′ is shaped differently from the above embodiment, which is formed by at least two latticed units 223′, wherein each of the latticed unit 223′ is circled by at least two bumped arms 224′. Each of the latticed units 223′ has two radial windows 225′ framed by the bumped arms 224′. The bumped arms 224′ are static during stirring the mixture 30′ which is pushed to flow in the inner spiral manner and has to be crashed into the bumped arm 224′ inside the beater device 21′. According to the embodiment, the bumped arm 224′ is preferably shaped into plate board which provides large surface to be bumped so that the mixture 30′ has more chances to be crashed. And the adjacent two latticed units 223′ are orthogonal with each other so that the mixture 30′ is passed through at least two of the latticed units 233′ while flowing from the inlet 11′ to the outlet 12′. The mixture 30′ is smashed into pieces by the baffle 22′ and fairly well-distributed to be increasingly thick.

The baffle 22′ has a first end 221′ received in one end of the freezing cylinder 10′ and a second end 222′ disposed on the supporting frame 211′. When the supporting frame 211′ is rotated driven by the motor 200′, the second end 222′ is retained statically respective to the supporting frame 211′. The second end 222′ has a groove to connect to the supporting frame 211′. And the supporting frame 211′ is rotated in the groove of the second end 222′ without rotating the baffle 22′. Therefore, the baffle 22′ is indirectly connected to the motor 200′ to decrease friction and abrasion against the motor 200′. Furthermore, the bumped arm 224′ of the baffle 22′ is similarly shaped as ladder for better stability to the supporting frame 211′. Even if the baffle 22′ is not connected with the supporting frame 211′, the baffle 22′ is capable of being supported inside the beater device 21′.

Another alternative mode of the baffle 21″ is illustrated in FIG. 7. The bumped arms 224″ are C-shaped to form the radial windows 225″ in D-shaped to be at least four latticed units 223″. The corner of the windows 225″ is rounded to avoid being filled with the mixture 30″. It is worth to mention that the baffle 21″ is also static against the rotating beater device 21″ while the stirring pusher 20″ is rotating to push the mixture 30″ from the inlet 11″ to the outlet 12″. According to the embodiment, the baffle 21″ has six windows 225″ radially opened for flowing through the mixture 30″. The mixture 30″ is crashed into the bumped arms 224″, then passed through the radial windows 225″. The mixture 30″ become more smooth and in smaller pieces in inner spiral flowing path.

One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

It will thus be seen that the objects of the present invention have been fully and effectively accomplished.
